public class HelloWorld {
static int score1 = 86;
static int score2 = 92;
public static int sum() {
int allScore=score1+score2;
return allScore;
}
public static void main(String[] args) {
int allScore = sum();
System.out.println("总分：" + allScore);
}
}
成功输出总分，下面那个平论mian方法里面引用方法allScore()没有传入参数
public static int sum(int a, int b) {
int sum = a + b;
return sum;
}
public static void main(String[] args) {
int allScore = sum(score1,score2);
System.out.println("总分：" + allScore);
}
}
